Description

Technical Field

[0001] The utility model relates to the technical field of coal processing equipment, and particularly relates to a flotation device. Background Art

[0002] During the formation of raw coal, various mineral impurities are mixed in. Inevitably, during the mining and transportation processes, rocks from the roof and floor and other impurities (such as wood, metal, and cement components, etc.) are also mixed in. With the improvement of coal mining mechanization and the change of geological conditions, the quality of raw coal will become worse and worse. In order to reduce the impurities in raw coal, coal preparation is required. Coal preparation is to use the different physical and physical-chemical properties of coal and other minerals to mechanically remove the impurities in raw coal in a coal preparation plant and divide it into products of different qualities and specifications to meet the requirements of different users. There are many types of coal preparation methods, which can be generally divided into two categories: wet and dry coal preparation. Coal preparation carried out in water, heavy liquid or suspension is called wet coal preparation. Heavy medium coal preparation and flotation coal preparation both belong to wet coal preparation. During the flotation coal preparation process, a large amount of foaming agent needs to be added, which will generate a large amount of bubbles. After coal preparation, coal particle foam will remain in the flotation cell.

[0003] To solve the above problems, referring to the prior art CN218796541U - a coal mine coal preparation flotation device, which includes a pool body, and moves through the fixed plate and filter screen at the top of the pool body. The filter screen pushes the foam floating on the water surface for cleaning. However, the water level in the pool body is variable, so that the height of the foam floating on the water surface is also variable. And the prior art cannot adjust the height of the filter screen and the partition board, so the foam layer at different heights cannot be cleaned. Summary of the Utility Model

[0004] The utility model aims to provide a flotation device to solve the problem that in the prior art, the height of the filter screen and the partition board cannot be adjusted, so the foam layer at different water levels cannot be cleaned.

[0005] To solve the above problems, the utility model provides the following technical solutions:

[0006] A flotation device includes a pool body. A motor is fixedly arranged at the top of the pool body. A reciprocating lead screw is driven by the movable end of the motor. The reciprocating lead screw is connected with a ball nut. The ball nut is fixedly connected with a fixed plate. A cylinder is fixedly arranged on the fixed plate. The movable end of the cylinder drives a filter screen. A partition board is fixedly arranged on the pool body. A plurality of partition plates are fixedly connected in sequence from top to bottom at the top of the partition board.

[0007] The working principle and beneficial effects of the utility model:

[0008] According to the water level height in the pool body, one or more corresponding partition boards at the top of the partition are disassembled, so that the sum of the heights of the remaining multiple partition boards and the partition is exactly parallel to the water level in the pool body. Then, the water in the pool body above the topmost partition board carries a part of the foam and discharges it outward. Most of the foam will remain in the pool body after leakage, and the floating foam is located above the topmost partition board. At this time, the cylinder is driven to move the fixed plate towards the direction inside the pool body, so that the filter screen is inserted into the foam layer. Then, the motor drives the reciprocating lead screw to rotate, and the reciprocating lead screw drives the fixed plate to move through the ball nut. The filter screen pushes the foam at the top of the pool body out of the pool body from above the topmost partition board.

[0009] In this solution, the height of the filter screen is changed by the cylinder, and the partition board is disassembled to meet the foam layers at different water level heights, so as to clean the foam layers at different water level heights.

[0010] Optimally, the fixed plate is slidably connected to the top of the pool body, and the sliding direction of the fixed plate is parallel to the movable end of the motor. This optimized solution defines the sliding direction of the fixed plate, making the movement of the fixed plate smoother.

[0011] Optimally, a bearing is connected to the movable end of the motor, and the bearing is fixedly connected to the pool body. The movable end of the motor rotates on the bearing, and the rotation is smoother.

[0012] Optimally, a drain pipe is fixedly provided on one side of the pool body relative to the partition board. The foam pushed out by the filter screen is discharged to the outside through the drain pipe.

[0013] Optimally, the width of the filter screen is the same as the width of the pool body. The filter screen extends to both sides in the width direction of the pool body, and the filter screen removes more foam.

[0014] Optimally, the number of the partition boards is 3 - 5. Description of the Drawings

[0018] The following is further detailed through specific embodiments:

[0019] The reference numerals in the accompanying drawings of the specification include: filter screen 1, motor 2, cylinder 3, fixed plate 4, ball nut 5, reciprocating lead screw 6, notch 7, pool body 8, drain pipe 9, partition 10, partition board 11.

[0020] In the following statements, orientation terms such as "left", "right", "up", and "down" are based on the orientation shown in the figures. In practice, if the corresponding structures are changed in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0021] Embodiment: A flotation device, as Figure 1 shown, includes a pool body 8. A motor 2 is fixedly provided at the top of the pool body 8. A reciprocating lead screw 6 is driven by the movable end of the motor 2. The reciprocating lead screw 6 drives a ball nut 5 (the reciprocating lead screw 6 and the ball nut 5 are in threaded connection). The ball nut 5 is fixedly connected to a fixing plate 4. A cylinder 3 is fixedly provided on the fixing plate 4. The movable end of the cylinder 3 drives a filter screen 1. The pool body 8 is fixedly provided with a partition plate 10. Three partition plates 11 are fixedly connected to the top of the partition plate 10 in sequence from top to bottom by bolts.

[0022] As Figure 2 and Figure 3 shown, in this solution, according to the water level height in the pool body 8, a corresponding partition plate 11 at the top of the partition plate 10 is disassembled, so that the sum of the heights of the remaining two partition plates 11 and the partition plate 10 is just parallel to the water level in the pool body 8. Then, the water in the pool body 8 above the topmost partition plate 11 carries a part of the foam and discharges outward. Most of the foam will remain in the pool body 8 through leakage. The floating foam is located above the topmost partition plate 11. At this time, the cylinder 3 drives the fixing plate 4 to move towards the inside of the pool body 8, so that the filter screen 1 is inserted into the foam layer. Then, the motor 2 drives the reciprocating lead screw 6 to rotate, and the reciprocating lead screw 6 drives the fixing plate 4 to move through the ball nut 5. The filter screen 1 pushes the foam at the top of the pool body 8 out of the pool body 8 from above the topmost partition plate 11.

[0023] In this solution, the height of the filter screen 1 is changed by the cylinder 3, and the disassembly of the partition plate 11 is coordinated to meet foam layers at different heights, so as to clean foam layers at different heights. Each partition plate 11 can be adjusted according to actual needs.

[0024] In addition, to make the movement of the fixing plate 4 smoother, the fixing plate 4 is slidably connected to the top of the pool body 8, and the sliding direction of the fixing plate 4 is the same as the moving direction of the ball nut 5.

[0025] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the records in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
